The GUI interface of chrom tools makes it very easy to use by even newbies like me who has never used any other chemical data management tool before! It is also quite intuitive that you can do most tasks without ever having to open up another window or tab while using this application. I have not found anything in particular which would be considered as an inconvenience but there are some minor issues with ChromTools such as sometimes when i am trying to edit multiple files at once it will crash (but only if its running low memory). As stated above, nothing really stands out from my experience so far since they're all relatively similar programs within their own categories/features. This is one program where you should give them a try because it does exactly what it says on paper - no more, no less. We are managing our chemistry laboratory inventory system through this software along with creating custom reports for various departments under us.
